Amy Coney Barrett, US President Donald Trump’s Supreme Court nominee, is going before the Senate Judiciary Committee for what could be a fiery confirmation hearing over the next four days.
The 48-year-old conservative jurist has vowed to judge legal cases impartially.
Judge Barrett’s nomination so close to the 3 November presidential election has sparked a political row between the Republicans and rival Democrats.
Judge Barrett’s approval would cement a conservative majority on the top court.
Conservative-leaning justices would then hold a 6-3 majority, shifting its ideological balance for potentially decades to come.
President Trump picked Judge Barrett to replace liberal Justice Ruth Bader Ginsburg, who died last month aged 87.
The Republicans – who currently hold a slim majority in the US Senate, the body that appoints Supreme Court judges – are now trying to complete the process before Mr Trump takes on Democratic rival Joe Biden in the election.
